The CM1231-02SO is a 2-channel electrostatic discharge (ESD) suppressor / transient voltage suppressor (TVS) diode series manufactured by ON Semiconductor. This series is a dual channel device with two ESD suppressors / TVS diodes built into one package. It is designed to protect sensitive electronic components from electrostatic discharge up to 8 kV and transient voltage surges up to 17 V. The device features low clamping voltage, low leakage current, and low capacitance. It is available in a small SO-8 package, reducing the board space requirements. The CM1231-02SO is ideal for various protection applications, including portable equipment, automotive, industrial, and consumer electronics.
